SASH-FASTENER.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed April 11, 1917. Serial No. 161,106.

To all whom it may concern:

Be it known that I, JOHN F. ArrnLL, a citizen of the United States, and resident of St. Louis and State of Missouri, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification, containinga full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to certain new and useful improvements in sash fasteners, and has for its special object the construction of a sash fastener employing a single locking means for locking both the upper and lower sashes in any desired adjustment.

In the drawings, Figure 1 is a transverse sectional elevation with parts broken away of the window casing and upper sash.

Fig. 2 is a section taken on the line 2-2 of Fig. 1, and

Fig. 3 is a side elevation, with parts broken away, of one of the jambs of the window casing, showing my invention applied thereto,

Referring to the drawings, 4L indicates the outside strip of the window casing, 5 the inside and 6 the jamb. 7 indicates one of the side rails of the upper sash and 8 the side rail of the lower sash.

Formed in these rails are a series of depressions 9 and 10 respectively. 11 indicates an angular shaft having its outer end journaled in a bearing 12 secured to the inside of the outside strip 4, adjacent the jamb 6 and having its inner end journaled in a plate 13 secured to the front face of the strip 5. r

The angular shaft or rod 11 is mounted in the window casing substantially on a level with the meeting rails of the upper and lower sashes, but not in a position to interfere with the operation of the weights, and is provided with a single operating handle 14 mounted on its inner end.

The handle 14 is nonrotatably mounted on the shaft 11 and by the operation of this single handle either the upper or lower sash may be locked at any desired adjustment. The fastener for both sashes is made out of a single piece of spring wire and comprises a coiled portion 15 nonmovably mounted on the shaft 11 about centrally of said shaft. Leading from the coiled portion 15 are elastic arms 16 and 17, the arm 16 being provided with a portion 18 arranged at an angle and the arm 17 is provided with a portion 19, arranged at an angle. Said portions 18 and 19 project in opposite directions and the portion 18 is provided with a horizontal portion 20, which acts as a locking pin and is adapted to pass through an opening in the jamb- 6 and having its free end located in the recess 9 of the upper sash for locking the upper sash, whereas the portion 19 is provided with a horizontal portion 21 adapted to pass through an opening in the jamb 6 and to be seated in the recesses 10 for looking the lower sash.

In Figs. 1, 2 and 8 both sashes are shown locked in a closed position by means of the portions 20 and 21 of the fastener, which are spring held in the depressions or recesses 9 and 10. When the sashes are thus locked the arms 16 and 17 are in vertical alinement, or you might say located in the same vertical plane'and the resiliency or elasticity thereof holds the portions 20 and 21 in a normally yielding engagement with the side rails of the sashes.

In Fig. 2 I have shown in dotted lines the operation of unlocking or unfastening the lower sash which is accomplished by means of turning the handle 14: toward the right in Fig. 1. By applying suflicient force to-the right, the portion 21 is disengaged from the recess or depression in the lower sash in order to unfasten the same.

During this operation the arm 16 will be bent or bowed inwardly toward the facing or jamb 6, as illustrated by the dotted line in Fig, 2, wherein the position of both arms in unfastening the lower sash is shown in dotted lines.

If it is desired to unfasten the upper sash and leave the lower sash fastened, the handle 1 1 is turned in the opposite direction and to the left, in which instance the portion 20 will be disengaged from the recess in the rail of the upper sash and the arm 17 will be bent or bowed inwardly.

From the foregoing it will thus be seen that I have provided an efiicient and simple locking device for both sashes, which may be easily applied to a window casing and by the manipulation of a single handle either sash may be unfastened independently of the other.

If desired, the arms 16 and 17 may be formed separate and each of the same secured to the shaft 11 in any desirable manner. In which instance, if said arms are properly spaced apart on the shaft, the portions 18 and 19 may be eliminated as these portions, as shown, are for the purpose of properly spacing apart the portions 20 and 21 to engage both sashes where the fastener is made out of a. single piece of wire.

Having thus fully described my invention, what I claim is A sash fastener comprising a shaft mounted transversely of a Window casing and adjacent to the meeting rails of upper and lower sashes positioned in said casing, a handle for said shaft, and a separate fastening device for both sashes formed from a single piece of spring wire and centrally mounted on said shaft, the said fastening device being provided with sprin arms projecting above and below said shaft, and each of which being provided with a portion lying in different vertical planes adapted to automatically engage suitable depressions formed in the window sashes for fastening the same and to be independently disengaged for unfastening one of the sashes independently of the other. 7

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

JOHN F. APPELL.
